I recently updated my amd64 machine to 13.2-RELEASE, which enables ASLR by default for 64-bit binaries. With ASLR enabled, running the binaries produced by dotnet occasionally (maybe 50%) of the time result in a SIGSEGV in the CLR. I have not troubleshooted in depth, but as a workaround, it appears that disabling ASLR for the binary fixes the problem: $ elfctl -e +noaslr binary This must be done for all binaries produced by `dotnet`.
